Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526990, here are decompositions:

  • 47 + 526943 = 526990
  • 53 + 526937 = 526990
  • 59 + 526931 = 526990
  • 131 + 526859 = 526990
  • 137 + 526853 = 526990
  • 227 + 526763 = 526990
  • 251 + 526739 = 526990
  • 257 + 526733 = 526990

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 526,990 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
